In carryingout the torinfot the invention, disclosed in thesetigurcs, l providenear each .end portion ot fthe spring A, an `auxiliary spring device designated generallyl vbythe numeral l, rthis spring device beingformed preferably Yt'roinv asingle length ot' suitable tempered-Wine or rod otpifopeigage bent into" elongated `rectangular toi-in ,to provide end portions2 and??y and ysides The end portions y 3 nterminate yin intereiigaging hooks 5I While the sidesft are, .formed at .spaced O points'With'coils or loops `6. In applying this auxiliaryspringdevice lto each end of the main spring A, the end 2 is eiigagedcbenc-,ath tliespring A `While ,the interengaged ends 3 are engaged over the top` thereof. kUse lis made,offelongated plates ,7 andS dis vposed respectively belou7 andyabove the snirino'` A the s rino' 7 cari: ino' AafU-bolt 9 l i 23 7 ,y Y h i y b which:entendsthrough one pail-.of loops or I eyes 6; The .plate member 8 ,carries Va depending ;U-bolt-.1O` which extends vbeneath theapring A; and vthrough the other pair oifeves oi' .loo srti' asjcleail shownin the drawings. It is y'preferable that the plate member 7 beneath `the spring ,belongitudi-A nally grooved or recessed `asindicated at ll Vton-the reception ot a` roller l1Q which tits' tliei ein and Which-bearsagainsttlie underside of the lowermost leaiv ofthe spring.,`

assembly A. i

VInstead otr-,providing a roller at this point,

vplate linay bensed instead of the plate 7 this plate 13 havingopenings 11i therethrough Within which areengaged bearing balls l5 and held in place bya leaf spring lt suitably anchored at the center ot the plate 13 as by a bolt 1T.

In Figures 7, 8 and 9, I have illustrated a moditied form of the invention, in which use is made of an auxiliary spring device 18 which is likewise ot elongated rectangular formation and which is made trom a single length ot spring wire or rod ot suitable gage bent to detine an end port-ion 19 and a pair ot' ends Q0, the tormer being disposable against the spring A and the latter against the top thereo't', the latter being furthermore in slightly spaced relation as indicated in Figure S. rIhe auxiliary spring 18 further includes sides 21 .termed intermediate their ends with loops Q2 located at the sides ot the spring Jr. Securing is etlected in this instance by means ot' a plate 23 disposed against the underside et the spring assembly A and carrying an upstanding Ubolt 2i passing through the loops or eyes 22 and engaging upon the top olf the spring assembly. I also provide a tie device Q5 which is likewise termed from a single length ot' wire bent to define an elongated portion Q6 disposed against the underside ot the spring A between the plate 23 and the ends 20, this member 25 being formed with coils 27. The tie device 25 is engaged beneath the spring A with the loops or eyes 27 receiving the sides Q1 ot the auxiliary spring device 18.

In Figures 1t) and 11, I have disclosed yet another modification in which the plate 23 and bolts 9.1 as well as the tie device 25 are all omitted. In this form of the invention, the auxiliary spring device 28, though ot rectangular form and including an end 9.9 and spaced ends 30 has its sides 31 'formed with loops 32 located at the sides of the spring A and engaged by a U-bolt 33 which extends downwardly from a plate 34 disposed on the top ot the spring A. This bolt 3S and plate 34 will be located at about the saine point occupied by the tie device 25 in the iorm shown in Figures 7 to 9 inclusive. At a point where the U-bolt 241j vas pw vided in the above mentioned figures, I have disclosed, in Figures 10 and 11, ay simple bolt or double headed rivet 35 resting upon the top ot the spring A and engaging beneath the upwardly lexed sides 3l.

In all forms ot the invention, it is preterahle that the same auxiliary spring device be located at. both ends ot the main or leat spring. Furthermore, in all vterms it is clear that the operation will be the same inasmuch as the pressure at. one end ot the auxiliary device is downwardly upon the top oi the spring A near its end while the pressure at the other end ot the auxiliary device is upwardly against the leaf spring.

In all instances there are provided two fulcrum points for the sides of the auxiliary devices so that there will be a double leverage exerted and as these auxiliary devices have considerable natural resilience it is obvious that they will greatly assist the main or ordinary springs and give them greater resilience as well as greater shock absorbing and rebounding preventing qualities. 'lt is really thought that the construction, operation and advantages will bc readily apparent to one skilled in the art Without further explanation.

VWhile I have shown and described the l'n'et'erred embodiment oit the invention, it should be understood that I reserve the right to make such changes in the itorm, construction and arrangement ot parts as will not depart irom the spirit oi the invention or the scope oi the subjoined claims.

Having thus described the invention, I claim:

1. A shock absorliing attachment tor a vehicle spring, comprising an elongated substantially rectangular resilient spring member having one end disposed beneath and its other end disposed above the spring, and means eng gn Y said spring member at the sides thereot tor effecting iiexurc thereof.

2.1i shock absorbing attachment lor a vehicle spring, comprising an elongated spring member having one end disposed benea 'h and the other end disposed above the vehicle spring, and tulcrnm elements engaging the sides o't` the spring member at spaced points and located respectively above and below the vehicle spring tor tlexing portions ot the sides ot the spring member in ditllerent directions.

3. A shock absorbing attachment: `tor a vehicle spring, comprising an elongated sln'ing member located at each end ot the vehicle spring and each having one end engaging beneath and the other end engaging' above the vehicle spring, the sides ot the spring member being 'termed with loops or eyes, transversely arranged elements extending through said eyes and other transversely extending tie means engaging the sides ot the spring member Al'or contining the same toward the vehicle spring and etl'ecting tlexure.

et. A shock absorbing attachment Vl'or a vehicle spring, comprising an elongated spring member ot substantially rectangular shape having one end disposed beneath the vehicle spring and its other end disposed above the same, and means engaging the vehicle spring and the spring member at intermediate points ol the latter tor ctl'ect-ing tlexure tllereoli upon movement ot' the vehicle spring.

In testimony whereof I atiix my signature.
